Anomalous Aortic Origin of the Right Coronary Artery: Invasive Haemodynamic Assessment in Adult Patients With High-Risk Anatomic Features.

ABSTRACT: Anomalous aortic origin of a right coronary artery (AAORCA) with an interarterial course merits further evaluation; however, robust risk assessment strategies for myocardial ischemia and sudden cardiac death are currently lacking. The aim of this study is to explore the potential role of fractional flow reserve (FFR), instantaneous wave-free ratio (iFR), and intravascular ultrasound (IVUS) in patients with AAORCA. Consecutive adult patients with AAORCA with an interarterial course were included. Computed tomography angiography, noninvasive ischemia detection, and FFR, iFR, and IVUS were performed at baseline and during adrenaline-induced stress. External compression was evaluated with IVUS. Eight patients (63% female, mean age: 53 ± 9.5 years) were included. Five patients (63%) were sympto
